OPPO BDP 103/105, sound quality???

I understand the difference between the 103 and 105 is more than just balanced outputs.  If OP is sure to use only HDMI output, then a 103 might the obvious economic choice; if analog output is a possibility, then a 105.  Even if OP thinks use will be HDMI, a 105 provides flexibility for future analog use.

I was also thinking of a 103 or 105 to replace my Sony SCD777ES SACD player which is now a boat anchor.  I would be running the player through the dac in my Parasound integrated amp(ESS Sabre dac) using the coaxial digital out and use the analog section of the player for SACD only.  Do you think I can get away with using the 103 instead of the 105 in my particular case?

dpphd,
No, HDMI only for video, definitely more concerned about 2 channel
audio quality. I do have a new Jolida tube DAC that in fact may prove to be a viable option to the 105's Sabre dacs. I'd hate to spend additional $600 if my external dac is superior.

Thoughts?
